.SH DESCRIPTION
.sp
.LP
The TSALARM interface provides functions through which alarm relays can be
controlled. The set of functions and data structures of this interface are
defined in the \fB<tsalarm.h>\fR header.
.sp
.LP
There are four alarm relays that are controlled by ILOM. Each alarm can be set
to "on" or "off" by using \fBtsalarm\fR interfaces provided from the host. The
four alarms are labeled as \fBcritical\fR, \fBmajor\fR, \fBminor\fR, and
\fBuser\fR. The user alarm is set by a user application depending on system
condition. LEDs in front of the box provide a visual indication of the four
alarms. The number of alarms and their meanings and labels can vary across
platforms.
.sp
.LP
The \fBtsalarm_get()\fR function gets the state of \fIalarm_type\fR and
returnsit in \fIalarm_state\fR. If successful, the function returns 0.
.sp
.LP
The \fBtsalarm_set()\fR function sets the state of \fIalarm_type\fR to the
value in \fIalarm_state\fR. If successful, the function returns 0.
.sp
.LP
The following structures are defined in \fB<tsalarm.h>\fR:
.sp
.in +2
.nf
typedef struct tsalarm_req {
     uint32_t     alarm_id;
     uint32_t     alarm_action;
} tsalarm_req_t;

} tsalarm_resp_t;
